EQUALIZING MECHANISIVI FOR PAPER-WIDING APPARATUS.

SPECIFICATION forming part of Letters Patent No.. 429,497', dated J' une3, 1890.

Application iiled February 15, 1890. SerialNo. 340,621. (No model.)

To all whom t may concern:

Be it known that I, CHARLES D. BINGHAM, of Watertowm'in the State of NewYork, have invented a certain newr and useful Improvement in EqualizingMechanism -for Paper- Vinding Apparatus, of which the following is aspecification.

My invention relates to that part of or appendage to a paper-makingmachine known as the winden and which is the part where the finishedpaper is wound into rolls of desired width and diameter. In all caseswhen the sheet of paper as it comes from the papermachine is dividedlongitudinally for the purpose of making two or more rolls from onesheet, it is necessary that each reel upon which the paper is woundshould take the paper from the slitters where the sheet is divided atabsolutely the' same rate of speed; and unless all the rolls aremaintained at exactly equal diameters the different surface speeds wouldproduce different tensions in the sheets going onto the several rolls.It is obvious that if a roll of smaller diameter be revolved enoughfaster than one of alarger diameter, so that each shall have the sameperipheral speed, then the paper will be wound upon each with the samedegree of tension; and the object of my invention is to supply a devicewhich accomplishes this result automatically. This feature is notbroadly claimed by me, for I am aware that devices have before beeninvented and used to attain the same end.

The main characteristic of my invention is the arrangement of partswhereby I am enabled to assemble and concentrate the entire equalizingmechanism for any desired number of rolls upon one and the same shaft,thereby greatly economizing space and material.

The nature of my invention and the manner in which the same'is or may becarried into effect can best be explained and understood by referencetothe accompanying draw` elevation, partlyin section, of the maindriving-shaft, the parts directly secured thereto, and the devices withwhich they are immediately associated. Fig. 5 is a plan of thepinion-locking devicein connection with the pinions which it controls.Figs. 3, 4, and 5 are upon a scale larger than Figs. 1 and 2. e

Referring to Figs. l and 2, M is the sheet of paper as it leaves thefinishing-rolls of the paper-machine. It passes between the slitters N,where it is divided into four strips of desired width,which are woundupon the reels O O2 O3 O4 of any suitable kind, power beingcommunicated. to the reels through couplings of any desired form, whichconnect the shafts of these reels with the Winder-shafts P P? P3 P4. Thewinder-shaf ts are revolved from the main shaft S by means of chains andsprocket wheels, as shown; but these sprocket-wheels and chains can bereplaced by gearing, belted pulleys, or any other usual appliance fortransmitting power.

R is a pulley to which the primary power is applied.

Thus far there is nothing new in the machine. I proceed noW to adescription of the mechanism in which my invention is comprised,referring for this purpose more par'- ticnlarly to Figs. 3, 4, and 5.

Keyed fast to shaft S and revolving with it is the hub A, having ondiametrically-opposite sides the counter-balance A and the arm A2,carrying pinions B B2 B3 B4. Pinions B B2 are keyed to shaft J ,which isjournaled-in arm A2, and pinion B meshes with pinion-B3. Pinions B3 B4are fastened together, forming practically one pinion of double width offace and revolving upon a stud K, havingits support in arm A2, as shown.Pinions B2 B4 mesh, respectively, with gears C C', the one of which iskeyed fast to or formed in one with the sleeve D, and the other of whichis keyed fast to or formed in one with the sleeve D. These two sleevesare mounted 'independently of each other uponl shaft S,

and can revolve freely thereon, except ascontrolled or driven by thepinions B2 B4.

To each of the sleeves D D is keyed fast a hub o, similar-to the hub A,except that they are bored large enough to iit the sleeves, and, likethe latter hub, provided with a counter-balance a and an arm a2,carrying IOO the same arrangement of pinions b', zc., as the arm A2 ofthe primary hub A. In the drawings pinion b3 is not shown, beingobscured, as in Fig. 3, by the pinion b', which is in front of it; but,as already remarked with reference to pinions B3 B4, the pinions b3 b4are practically one piDiOn 0f double width of face. i

Revolving freely upon the Sleeves D D', except as controlled by pinionsh2 b4, JISWo upOll each sleeve, are gears E, which mesh, the one withpinion b2, the other with pinion b4, said gears being fastened solidlyto or forming part of sprocket-wheels F. Each of these foursprocket-wheels is by a chain connected to the Winder-shaft P', the.,appropriate to it. It will be noted that throughout this arrangement Imake use of spur gears and pinions, and this I prefer, because suchgears and pin ions can be much more easily and cheaply made,commercially, than bevel gears and pinions. Still, if desired, thelatter might be used instead, in which case, in lieu, for instance, ofthe four pinions I5 B2 B3 B4, there would be journaled on arm A2 upon avertical axis a beveled pinion to mesh directly with the gears C C',which of course in this event would be correspondinglybeveled. By thisarrangement all the equalizing devices for the several Winder-shafts areassembled, supported, and move upon one and the same dri ving-shaft S.In this system each sprocketwheel is a fulcrum for all the others, andthe size of the gears being uniform the power communicated from shaft Sto any sprocketwheel will exactly equal that communicated from it to anyother one of the set. If any three of the sprocket-wheels are held fastwhile the shaft S is revolved, the remaining one will revolve at four,times the speed ol' the shaft; or, if two are held fast the remainingtwo will revolve at twice the speed of the shaft. The outersprocket-wheels and their gears are kept from endwise movement on thesleeves by collars G on the latter, and the sleeves in turn aresimilarly confined by collars I-I on the shaft S.

It is obvious that the same system may be extended indenitely-eg.,toeight, sixteen, or a greater number of sprocket-wheels driving acorresponding number of reels-byinereas ing the number of sleeves withthe necessary additional arms and gearing, still using one central shaftS only.

If it be desired at any time with a fourreel Winder-such as representedto wind a less number of rolls than four-this may be done by locking oneor more of the pinions, thus compelling the gears on each side of therevolving driving-arm to revolve as one. For this purpose I provide alocking device, which, preferably, is of the construction shown insection in Fig. 4 and in plan in Fig. 5. This device consists of a pin5p, capable of longitudinal and rotary movement in a barrel A3 on armA2. The inner end of this pin projects through the inner end of thebarrel and is shaped to fit intothe spaces between the teeth of theApinion B4. The pin is spring-pressed toward the pinion by a spiralspring s in the barrel, encircling the pin and confined between ashoulder on the latter and the outer end of the barrel. The pin isprovided with a head or button, by which it may be pulled back out ofengagement with the pinion; and it has on it a laterallyprojecting studor spline p', which moves in a groove p2 in the barrel. Then the pin ispulled out far enough to bring the spline outside of the groove, it canbe held in a retracted position by turning it so as to throw the splineout of register with the groove. As soon as the spline is brought againinto register with the groove the pin is free to again move inward intoengagement with the pinion. I do not recommend, however, that a fourreelwinder be used for winding three rolls, except temporarily, as it isobvious that such an arrangement winds one of the rolls with the sametension as both of the others, or, in other words,with twice the tensionof either of the others. So for winding three rolls I prefer to supply athree-reel Winder, which has the third reel driven by a gear and pinionof such relative proportion to the gears and pinions driving the othertwo reels that the third reel will have a tension upon the paperone-half that of the other two or the same as either of the other two.

Having described my invention and the best way now known of carrying thesame into effect, what I claim, and desire to secure by Letters Patent,is

The combination,with the primary drivingshaft and the primarydriving-arm and gearing carried by and revolving with the same, ofseparate and independent sleeves or tubular secondary shafts mounted torevolve freely on said primary shaft, gears fixed to said sleeves tomesh with the gearing of the driving-arm on the primary shaft, secondarydriving arms-one for each sleeve--iixed thereto, gearing carried by saidsecondary driving-arms, respectively, and gears mounted to revolvefreely on said sleeves and engaging the gearing carried by the secondarydriving-arms, under the arrangement and for joint operationsubstantially as hereinbefore set forth.

In testimony whereof I have hereunto set my hand.
